摘要

摘 要
本論文研究使用石化製程五大設施(設備元件，儲槽，排放管道，裝載，與廢氣燃燒塔)以「洩漏、偵測、及修護」法與「排放、偵測、及防制」法的20家廠商檢測結果，來計算揮發性有機物的排放量。這些揮發性有機物的削減量然後可以在石化業廠商的改善及第二次複檢工作之下計算獲得。
對於所有石化製程的五大設施，「揮發性有機物空氣污染管制及排放標準」法定的生效最遲日期是1999年的7月1日。因此，本研究的計算結果，可能是全國為石化製程5大設施VOCs總排放量及總削減量數據所建立的第一套資料庫系統。
本研究在石化業者進行污染改善前，5大設施VOCs總排放量的計算結果為11,439.71噸/年。本研究之VOCs總削減量為7814.19噸/年。因此，本研究之VOCs的總削減率為68.31%。
本論文研究已成功地發展了一套計算模式，來估算石化製程五大設施的VOCs排放量與削減量。計算結果呈現本研究之方法已對20家石化業廠商的VOCs排放量產生顯著的減量效益。因此，本論文研究的技術未來將會被廣泛地應用在台灣，以有效而且實質的降低全國的VOCs排放量，那是可以預期的。

Abstract
In this study, the examined results of the the volatile organic compounds (VOCs) of the 5 operating facilities (the equipment component, the tank, the vent pipe, the loading rack, and the flare) of the petrochemical processes using the leak, detection, and repair (LDAR) method and the emission, detection, and protection (EDAP) method for the 20 petrochemical factories are employed to compute the VOCs emission rates. Their reduced emission rates of VOCs may then be obtained if the second examination of the LDAR method and the EDAP method is done after the improvement works of air pollution problems are finished by the masters of the petrochemical factories.
For all of the 5 operating facilities of the petrochemical processes, the legal latest date of the Air Pollution Control and Emission Standard of VOCs of the Environment Protection Agency (EPA) in Taiwan is July 1 of 1999. Thus, the computational results of this study may be the first data bank system in Taiwan about the total emission rates and the total reduced emission rates of 5 operating facilities of the petrochemical processes.
The computed total VOCs emission rate of the 5 operating facilities before the improvement works of the masters of factories are finished is 11,439.71 tons/year. The computed total reduced VOCs emission rate is 7814.19 tons/year. Thus, the total reduction rate of the VOCs emission rates computed in this study is 68.31%.
In this study, a computational model is successfully developed to evaluate the VOCs emission rates and the VOCs reduced emission rates of the 5 operating facilities of the petrochemical processes. The computed results present the significant effect to reduce the VOCs emission rates from the 20 petrochemical factories. Therefore, it can be anticipated to use extensively this technique of this study in Taiwan in future to reduce effectively and essentially the VOCs emission rates of all petrochemical factories.
